ChimeraX 1.7 won't start when initial window size setting is "maximized"

Hello,

After installing ChimeraX 1.7, the GUI will not open. ChimeraX 1.6.1 is fine:

'width' used before set

Fixed in daily build (Dec 22, 2023) and 1.7.1 release (if and when it is made).

This bug happens when the "Initial overall window size" setting in ChimeraX has been changed to "maximized". To work around this bug in ChimeraX 1.7, start ChimeraX 1.6.1 and change the Initial overall window size setting to a different choice (e.g. "last used") and save that setting. Then ChimeraX 1.7 will start.
